If asking for DO_RIDGING without Icepack, one gets:

FATAL from PE    14: nilyr or nslyr mismatch with Icepack

It would be nice to having it instead say that DO_RIDGING is not available without linking in Icepack/columnphysics.

Thanks for pointing this out @kshedstrom . It is an accurate, but useless error message. I will send a PR with a more useful message informing that actual Icepack code needs to be included in the compilation of the model, rather than the stub code in config_src/external

Icepack area underflow patch (#184)
f6b58b7 
New parameter RIDGE_AREA_UNDERFLOW is introduced in order to avoid the occurrence of undetectably small fractional area and negative ice volume following ridging adjustments from Icepack. The default is 0.0, which does not introduce changes in existing runs. A reasonable value would be 10^-26 which would correspond to an Angstrom-scale ice patch within a km-scale grid cell. This addresses #178 and #183
